APPTUS FQR @IL hppltcation filed march 12 To (/71 whom it may concern:

it known that 1, Jenny D. NIXON, a c tizen of the United States,residing at the city of Oklahoma, in the county of @klahoma and State ofOklahoma, have invented certaln new and useful Improvements in Apparatusfor Pumping Oil, of which the following is a specification.

This invention relates to oil wells and has tor its object increase ofthe length of time that the pumping apparatus within a' well can be usedwithout cleaning and also has another purpose, the reduction of theamount of sand friction and consequent wear of the parts.

In the accompanying drawings forming part of this specification, inwhich like num bers of reference denote like parts wherever they occur,the figure is a vertical longitudinal sectional view.

The well 1 within the earth 2 is in the usual form. Gil, sand, and mud,are present at 3 mixed together. The casing supporting the sides of thewell is not shown in the drawings.

The tubing anchor 4 is in the usual vform, heing a hollow cylinder andadapted to allow the oil etc. 3 to pass through it into the gas anchor5. The standing-valve anchor 6 is hollow and is interiorly threaded at 7and 8 for the attachment thereto, respec tively, of the tubing anchor aand gas airchor 5.

Shoulder 9 serves as a seat for the barrel or tube 10, which isinteriorly threaded at 11 so as to screw upon the threads on the top ofanchor 6.

Such heavy matter as sand and mud 12 as is deposited out of the flowingoil in the manner hereinafter described rests upon the top surface oredge of standing valve anchor 6.

By the construction, arrangement, method of operation, and process ofhandling the oil with the sedimentary matter contained therein, thequantity of sediment that may be accumulated within the barrel 10 isincreased about one hundred fold over what is possible in suchapparatuses at the present time, and. moreover, less sand and othergritty matter'reaches the working valve 13, and. therefore, friction andwear and tear on the said valve 13'and the working barrel it, in whichthe same reciprocates, are greatly diminished. en an a paratus such asthis is filled to its capacity with sand,

mud, etc, it is necessary by means of machinery to pull out of the well"the entire pumping apparatus, the length or extent of which is as great.as the depth of the well, which, as is well known, is often more than2,000 feet. which these parts are extracted from the well for cleaningmeans not only a saving in labor and expense, but also increases theoutput of the well because of less frequent interruption of theoperation of the pump.

. The suction by means of working-valve l3 draws the oil and itssedimentary contents through the passages within tubing anchor l, gasanchor 5, and standing-valve anchor 8 and through the pipe 15(threadedly connected at '15 in the head of anchor 6 and at To reducethe frequency withits opposite end by threadl? within cage 18) and thesaid pipe 15 conducts the oil etc. to the battle-bell 19 supported uponcage M and bushing 2%:and pipe 25 and thence outwardly to the surface ofthe ground.

The direction of ilow of the oil and its sedimentary contents isindicated by the arrows in the drawing, the long arrows denoting oil theshort arrows the sand, mud, etc,

The tortuous course of these materials downward within bell l9 andaround the edge 21 thereof results in giving an opportunity to thesediment to settle to the point:- 12 and results in the oil being, to avery considerable extent, freed therefrom before reaching the workingvalve 13. Most of the oil that has passed valve 13 flows upward frombarrel 14: through bushing 24, but part 18 and fastened thereto by nut20. Thereof it is deflected by the lower edge 26 of The cross-sectionalarea of heme bell 19 is approximately that of the pipe or barrel 10'within which the same is contained.

The pi e 15 is so anchored to valve anchor 6 and poised in barrel 10free from magnetic contact with it that the magnetic circuit iscompleted only through anchor 6 exerting downward pull on the ball-valve29. This prevents the said ball 29 from rising from its seat and lodgingin the cage 18 above.

Having thus described this invention, I hereby reserve the benefit ofall changes in form, arrangement, order, or use of parts, as it isevidentthat many minor changes may be made therein without departingfrom the spirit of this invention or the scope of the following claims.

I claim:

1. In a sand arresting mechanism for oil wells, an upper and lower tubehaving a hollow coupllng therebetween, a barrel connected to thecoupling and in spaced relation to the inner wall of the upper tube, asucker operatively arranged in the barrel, an intake pipe arrangedaxially of the lower tube and adapted to communicate at its lower endwith the space in which the oil is stored, a valve ca e on the upper endof the intake pipe, a va ve in said cage, said cage naiaeae havingopenings in its side for the passage of oil, and a bafie supported bythe valve cage and guarding the openings for the passage of oi V 2., Inan oil well equipment, a tubing, an intake pipe therein through whichoil is circulated, a valve for controlling the-intake pipe, a hoodsupported above the valve and extending downwardly in spaced relation tothe inner wall of the tubing, and means below the depending hood forarresting foreign substances.

3. In a sand arresting mechanism for oil wells, an upper and lower tubehaving a hollow coupling therebetween, a working barrel connected to thecoupling in spaced relation to the inner wall of the upper tube, a

sucker operatively arranged in the working barrel, an intake tubearranged axially of the lower tube and adapted to communicate at itslower end with the space in which oil is stored, a valve seat on theupper end of the intake tube, a valve held in operative relation to thevalve seat, and a bafie supported above the valve and deflecting theflow of oil passing the valve.

In testimony whereof I hereunto afiix my signature.
